Shot Selection

At the end of last season, I took a look at Duke's shot distribution, and their success with each "type" of shot. The shots we have are 3pointer, dunk, layup, tip-in, and 2-point jumper. I noted that FG% on 2-point jumpers is usually bad (worse even than on 3pt shots), and thus teams should look to maximize dunks, layups, tip-ins, and 3s. Here's how Duke players (and the team as a whole) are dividing up their shots, and how they're doing on those shots (current through Michigan):

Here's a glossary for the categories:
FG - all field goals
2 - all 2-point field goals
3 - 3-point field goals
D - dunks
L - layups
T - tip-ins
DL - dunks and layups
DLT - dunks, layups, and tip-ins
O2 - all 2 point field goals that aren't dunks, layups, or tip-ins (broadly referred to as 2-point jumpers)
ND - all non-dunks
J - all jumpers (O2+3)

So far, Duke's distribution is 37.0% 3s, 35.8% DLT, and 27.2% other twos.

I know Duke's 2pFG% in the first 6 games has increased from about 53% to about 57%, but I wonder how much of that is related to shot selection? Do you have similar numbers for the team last year after 6 games?

Good stuff.

er, I meant it has improved since last year after 6 games.
